One group favour the theory that two different proto-gods were blessed by Sybel the Bounteous at the same time - and thus created different branches of the same race simultaneously. Others argue that Torag and Moradin are two different names for the same deity, and the different interpretations are down to the priesthood. Some argue that Moradin’s church was advised to reach for the sun earlier, and whuile they reached the surface, they abandoned the underdark completely - all settling in surface only mines. Another school of thought talks about a single deity, somehow split asunder, to create two founding deities … To say it is complicated, is an understatement.
